The SOwhich is contained in the exhaust gas is chemically adsorbed at the oxygen adsorbing and releasing material (54) without being oxidized. If the temperature of the SOtrap catalyst (13) becomes higher than the start temperature of adsorbed SOmovement, the SOwhich is chemically adsorbed at the oxygen adsorbing and releasing material (54) is oxidized and stored in the form of sulfates in the SOstorage material (55).",
